CARDING-ENGINE.

SPECIFICATION forming part of Letters Patent No. 600,882, dated March 22, 1898..

Application filed February 24, 1896. Serial No. 580,438. (No model.) Patented in England May 27, 1895, No. 10,374 and in,

France April 7, 1896, No. 242,731-

Be it known that I, GEORGE MARTIN, a subject of the Queen of Great Britain, residing at Southport, England, have invented certain Improvements in Scribbling or Carding Machines, (patented in England May 27 1895, No. 10,374, and in France April 7, 1896, No. 242,7 31,) of which the following is a specification.

This invention relates to improvements in scribbling or carding machines particularly applicable for carding wool and similar fibers; and its object is to more effectually open out and straighten the fibers.

To fully describe my invention, reference is to be had to the accompanying sheet of drawings, forming apart of this specification, in which similar letters of reference indicate corresponding parts in each of the figures.

Figure 1 represents such parts of a cardingmachine as are necessary to illustrate the application of my improvements. Fig. 2 represents a section of the same on the broken line a b of the former figure. In this figure the full width of the machine is not shown, as one side is practically the same as the other. Fig. 3 represents a view of a detail hereinafter referred to.

A portion of the side frame of the cardingmachine is represented by the letter A and is the crown of what is commonly called the bend of the frame, and B represents a portion of one of the swifts or cylinders. A plate 0 is fitted to the bend A on each side of the machine. In the drawings it is shown fixed between the webs A A of A by the setscrews 0 and it is also secured by the bolts 0 0 An adjustable bracket D is secured to each of the plates 0 by the bolts D D and adjusting screws D D are fitted in the brackets to engage the bolts D to facilitate adjustment. A bearing-piece E is secured on each side by a bolt E to the bracket D, and this bearing-piece is made vertically adjustable. Each bearing-piece is provided with a U -shaped bearing at the top, in which the shaft F, extending from one side of the machine to the other, is mounted. This shaft is driven in any convenient manner, but preferably by a belt or chain. A star-wheel G, of the usual form to receive the projections H on the ends of the flats H is fixed in position close to each end of the shaft, and a disk J is also secured on the shaft adjacent to each starwheel. These disks are provided for the backs H of the ends of the flats to bear upon and so relieve the pressure and friction on the teeth G of the star-wheels. A curved guidepiece K is fixed by the adjustable studs K K inside each of the brackets D. Screws K K are fitted into the slots D D in D to facilitate adjusting the studs K The flats are connected together in the usual Way by a chain L, connected by the screws L to the end faces of the projections H.

The shaft Fis driven in the direction of the arrow, Fig. 1, and the flats pass off the disk J under the guide-piece K,which are so formed and adjusted that the card-teeth H on the flats gradually approach the card-teeth B of the cylinder B. Oonsequentlyany sudden action on the fibers is reduced to a minimum.

To insure a smooth and uniform action, it is of the greatest importance that the backs of the flats should be held firmly and squarely against the guide-pieces K while they are acting upon the fibers. Therefore, besides keeping the chains at a suitable tension, the under guides N are provided on the inner face of the casting D. The upper or guide faces of the guides N are parallel to the guides K and are exactly the thickness of the ends of the flats away from the acting faces of the guides K. Consequently the flats are held with the requisite degree of firmness and truth while they are acting on the fibers. Fig. 3 represents a separate side view of one pair of guides K and N with the ends of the flats shown between them.

The castings D and the parts connected to them may be bodily adjusted to regulate the position of the flats in action on the fibers in relation to the swift cylinderB. Two or more of these sets of flats may be employed in connection with one swift or cylinder, and the card-filleting with which the flats of the different sets are covered may vary in count that is to say, in the number and strength of the dents or wire points.

A stripper S is shown in Fig. 1 on each side of the flats mounted in bearing-pieces S secured to the bracket D. It is not necessary to use the two strippers; but one may be used in either position. The bearing-pieces S also serve to carry a grinding-roller.

Having now particularly described and. as-

certained the nature of my said invention and in What manner the same is to be performed, I declare that what I claim is 1. In a scribbling or carding machine, thecombination with the frame or bend and a Y the upper or guide face of the piece N being parallel to the acting face of the piece K ing above, the revolving flats adapted to engage at their ends between the guide-pieces K, N, the said brackets and the guide-pieces K being adapted to be adjusted vertically in.- dependently of each other, and means for supporting and moving the flats.

2. In a scribblingor carding machine, the combination with the frame or bend, auda card-cylinder, ,of a plate secured to the frame on each side thereof, a bracket ,adjustably secured to each plate, a curved guide-piece K arranged upon the inner side of each bracket, said bracket being provided with vertical slots, studs carried by the guide-piece and projecting through the slots, and adjustingscrews projecting into the slots and adapted to adjust the studs, the guide-piece N secured to the inner side of each bracket below the piece K, the upper guide-face of piece N being parallel to the acting face of the piece K, the revolving flats adapted toen gage at their ends between the guide-pieces K Nand means forsupporting and moving the flats, as and for the purpose specified.

,Intestimony whereof I have hereunto set ,my hand in the presence of the two subscribe z g w ne s GEORGE MARTIN. 'Witnesses:
